Problem-solving videos as an instructional aid for engineering education

Described in this paper is the use of problem-solving videos as an instructional aid for teaching an introductory engineering circuit analysis course. The instructor prepared step-by-step video solutions, with audio, of classroom examples, homework problems, and examination solutions. The videos were accessed through a Website; as a result, they were available to the students twenty four hour per day and seven days per week. Web usage statistics indicate that the students were using the videos extensively as they studied course materials. Student surveys indicate that they believe that the videos were improving their understanding of the course material.
